TECHNICAL NOTES 4 VIBRATING SCREENS

4.1 Classification Based on Sieving - Vibrating screens The basic method of operation of a screen is very simple. The screen presents a barrier to the passage of oversize material while it readily passes undersize material. It is only necessary to ensure that each particle has an opportunity to reach the screen.
